Trond Myklebust 00bcbe119f pNFS: Don't update the stateid when replying NFS4ERR_DELAY to a layout recall
RFC5661 doesn't state directly that the client should update the layout
stateid if it returns NFS4ERR_NOMATCHING_LAYOUT in response to a recall,
however it does state that this error will "cleanly indicate completion"
on par with returning the layout. For this reason, we assume that the
client should update the layout stateid. The Linux pNFS server definitely
does expect this behaviour.

However, if the client replies NFS4ERR_DELAY, then it is stating that
the recall was not processed, so it would be very wrong to update the
layout stateid.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
